Right now this is MAC OS X only (Windows support coming soon).This version does not hacktivate the iPhone.You must have a clean install of the iOS 4.2.1 Firmware (Yes, this means restoring).As there are actually a couple of things you should know before just jumping the gun and jailbreaking your iDevice with GreenPois0n RC5.īefore following this tutorial P0sixninja, the developer of GreenPois0n has made it quite clear that: Regardless of this, I am still going to provide you with a tutorial on using GreenPoison RC5 to untether the iOS4.2.1 firmware. In fact they are so easy that a tutorial is not generally needed.

This iOS 4.2.1 untethered jailbreak is stable, does not require the iOS 4.2b3 SHSH blobs, and right now ONLY works with the Mac OSX operating system (Sorry Windows users… Support will be coming soon don’t worry).Īs I am sure you already know, using tools like GreenPois0n and LimeRa1n are extremely easy to use. Just about an hour ago GreenPois0n RC5 was released, and with this release comes a fully untethered iOS4.2.1 jailbreak.
